Numbers 16:27-30

27So they got away from the dwelling of Korah, Dathan, and Abiram. And Dathan and Abiram came out and stood at the door of their tents, together with their wives, their sons, and their little ones.

28And Moses said, "Hereby you shall know that the Lord has sent me to do all these works, and that it has not been of my own accord.

29If these men die as all men die, or if they are visited by the fate of all mankind, then the Lord has not sent me.

30But if the Lord creates something new, and the ground opens its mouth and swallows them up with all that belongs to them, and they go down alive into Sheol, then you shall know that these men have despised the Lord."
